Our Story

Our Beginnings

Dial One Roofing of Oregon, Inc. began as a partnership under the name Tri-County Roof Service, for the treatment of moss on roofs and sidewalks. The process was simply to spray a zinc based product on the moss, and then let it die and fall apart. While the process was effective, it was by no means fast, but the results were spectacular. Pressure washers were not a common item then, and were very expensive if you could find them at all.

Then on May 18th, 1980, it happened... Mount Saint Helens explodes pouring 2" to 3" of ash on everything in sight. Every roof needed to be cleaned off, every gutter cleaned out. Yards, patios, and patio furniture all had to be cleaned off, and the ash removed and disposed of. We purchased two pressure washers, and went to work. Fortunate for the company, the ash made moss grow on everything at an unstoppable rate, therefore constant work was available. For 4 years we did nothing but pressure wash roofs to remove moss and ash.
